The c.1447G>A (p.V483I) alteration is located in exon 11 (coding exon 8) of the SLC7A6 gene. This alteration results from a G to A substitution at nucleotide position 1447, causing the valine (V) at amino acid position 483 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
